You should be skeptical of industrial use case as well. Allowing any device with internet access and a camera on it onto the floor of most electronics manufacturing facility is a nonstarter, phones, smart glasses, or anything of that sort. The other thing is, smart glasses buy nothing over having PCs/assembly line machines with screens for HMI, and standard operating procedures can be printed on paper. Also, if you are actually an operator on an assembly line, wearing these glasses for 10 hours a day is the last thing you want at your job.

The case for them gets even worse for heavy manufacturing industry/trades, since you have to think about safety and liability now: what if these smart glasses fall into the machines and cause an accident? Can these smartglasses can withstand the environmental conditions in the workshop?
